English PW Need help with fusee repeater click

Hi everyone.

I am working on a fusee repeater.

The click for the repeater barrel/mainspring keeps falling out of its hole. It isn't enclosed in anything so after activating the repeater a few times, it just dislodges off into the movement. How is this supposed to stay in? if it is too tight, it probably wouldn't move and yet i can't see how it should stay in.

Assuming you mean the older style, about 1800, it is staked in from the back side. It looks like a teeny plain brass shaft on the back of the click going through a plain brass hole in the repeater mainspring drive wheel, but the hole is slightly tapered so when the click is in the hole and staked lightly with a ball stake from the back side it spreads the back end of the brass shaft, which holds it into the hole. The key is if the click shaft is long enough to go all the way through the hole and how hard you stake it, so it is held in OK, but can still turn by the click spring pressure into the catch teeth of the arbor plate. It is very similar to the time mainspring clicks underneath a fusee in this regard.
